PRESIDENT’S MESSAGE
In our Spring newsletter, I wrote of the prominence of energy and power-related
initiatives in Pennsylvania, and their undisputed link to water resources. The
quest to develop cleaner, alternative and renewable energy sources is among the
initiatives attracting the most interest – driven not only by threatened scarcity
of traditional fuels, but also by the desire to reduce carbon emissions to the
atmosphere.
The Union of Concerned Scientists (UCS) recently published information about
potential climate changes due to carbon dioxide and other greenhouse gases.
Water resources are obviously an integral part of the Earth’s climate, and any
changes to Pennsylvania’s climate could likewise have implications for the
Commonwealth’s water resources. For example, the UCS report cites predictions
for an increase in winter precipitation, but with more rain and less snow due to
increased average temperatures. It also points to data predicting an increase in
the frequency and severity of heavy rainfall – raising the likelihood of fl ooding
– and, at the opposite extreme, an increase in the frequency of summer droughts.
It is important that we, as water resource professionals, know how such changes
are affecting long-term hydrologic patterns.
Further complicating the matter is the reliability of hydrologic data. When
planning for water resource management, we typically avail ourselves of
valuable streamfl ow records stretching back one hundred years or more. But
are we certain that those records still reliably refl ect current conditions or
expected changing conditions? An investigation of streamfl ow records at
several long-term gages in the Susquehanna River Basin already shows a distinct
difference in patterns pre- and post-1970. Whether that shift is in response to
warmer temperatures, changes in rainfall distribution, construction of large
impoundments that alter fl ow regimes, changes to impervious cover and
stormwater runoff, or some other cause is not yet known.
Whatever the cause, the implications for water resources of climate change could
be extensive, and management, planning and protection cannot occur without
a good understanding of what the new natural patterns are, or how they are
expected to change. Also, although most focus has been on water quantity,
there is the potential for impacts to management of water quality as well. For
example, Pennsylvania’s Chesapeake Bay Tributary Strategy will be implemented
using assumptions about the entry of nutrients into Pennsylvania streams
and how they interact with natural systems, but those assumptions may vary
depending on factors such as average fl ows and water temperatures.
To learn more about the UCS publication, visit www.climatechoices.org. If
you’re interested in learning more about water resources in Pennsylvania, I
invite you to attend our annual fall conference, scheduled for October 12th
in Harrisburg. This year’s theme is focused on water quality and aspects of its
regulation and impairment. Plus, the conference will feature a keynote address
on the aforementioned Chesapeake Bay Tributary Strategy by leaders from the
Department of Environmental Protection. We hope you’ll consider joining us!

There is a need for accurate georeferenced
bathymetric data of
lakes and reservoirs throughout
Pennsylvania. Data collected
through this effort could be merged
with recently acquired LIght
Detection And Ranging (LIDAR)
land-surface-elevation data to
create a seamless elevation data
set. However, conducting highly
accurate bathymetric surveys
using conventional surveying
and fathometer methods is time
consuming. Recent advances
in equipment, data-collection
techniques, and supported
differential global positioning service
make it possible to produce highly
accurate digital products of lake-bed
elevations within a relatively short
period of time.
The Pennsylvania Department of
Conservation and Natural Resources
(PA DCNR) and the United States
Geological Survey (USGS) have
partnered to acquire geo-referenced
bathymetry for selected Pennsylvania
lakes and reservoirs. The program
will initially focus on western lakes
and reservoirs. The frequency and
number of echosoundings collected
for a given water body will depend
on the complexity of its bathymetry
and its areal size. For example, a
100-acre lake may require 100foot
spacings. The raw bathymetry
data will be processed to fi lter (1)
multiple-return acoustic signals in
shallow water, (2) corrupt GPS signals
(multipathing), and (3) redundant
areas along the banks caused by
equipment limitations (Figure 1).

Bathymetric Surveys of Pennsylvania’s
Lakes and Reservoirs
Analog printouts of the bottom
profi les will be produced and used as
a quality-assurance measure during
the processing phase.
The instruments used to defi ne the
lake bottom are a single-beam, 210
kHz echosounder and differentially
corrected-global positioning system
(DGPS). The data will be integrated
with a navigational software
package to collect georeferenced
bathymetric
data at predefi ned cross
sections. Differential
corrections will be provided
by a commercially available
service. The installation of
temporary staff gages at
several locations adjacent
to the lake will be used to
correlate the lake bathymetry
with the land surface. The
vertical elevation of the
staff gages will be surveyed
using a two- meter fi xed
height tripod with Ashtech
Z-12 receivers and Ashtech
Geodetic III “Whopper” Rev D.
L1 and L2 antennas (Figure 2). Data
reduction will be accomplished using
Ashtech’s AOS software.
At the conclusion of the data
collection phase, it is anticipated
that digital-bed elevations will be
generated along with a USGS Data
Series report, which will be used to
transmit the data and the results of
the program.

In 1992, the Susquehanna River Basin
Commission (SRBC) temporarily
suspended the application of its
consumptive water use regulations
for agricultural operations. In the
15 years since, SRBC has worked
with the agricultural community
to fi nd solutions for: (1) applying
the regulations equitably; and (2)
compliance with the consumptive
use regulations, particularly as they
apply to compensation during
periods of low fl ow.
Using funds from the Pennsylvania
General Assembly, SRBC
conducted two major efforts in
the Commonwealth
to fi nd solutions.
The fi rst involved
the study of the
George B. Stevenson
Reservoir in Cameron
County for possible
water storage. The
project was deemed
not feasible due to
expected costs in
excess of $43 million.
The second involved
the Pennsylvania
Agricultural
Consumptive
Water Use Study.
Under this study,
which concluded
in fall 2005, SRBC
projected agricultural
consumptive water
use through 2025
and reviewed various
compensation options
for the consumptive
use.

Barnes and Tucker Mine Water Treatment Project Will
Improve Environment and Support Farmers
Project is major step toward relieving PA farmers of consumptive water use
requirements
The study identifi ed as a potential
compensation option the use of
underground mine water storage.
Working with the Department of
Environmental Protection’s Bureau
of Abandoned Mine Reclamation,
SRBC staff decided to pursue the
Barnes and Tucker treatment project
for consumptive use compensation.
The treatment project, sponsored by
the Commonwealth with SRBC as a
proposed partner on the project, is
currently in the design phase with
construction estimated for spring
2008 through spring 2009. Because
the current Duman treatment system
(Figure 2), involving a diversion of
water from the Susquehanna basin,
is not effi cient, the Commonwealth
proposed to construct a treatment
facility at the Barnes and Tucker
site (Figure 3). The treatment plant
is expected to operate for 75 years
and result in the restoration of 25
miles of the acid mine drainage
(AMD)-impaired West Branch
Susquehanna; and provide enough
water to compensate for 10 million
gallons per day (mgd) of agricultural
consumptive water use during the
growing season by discharging water
into the Susquehanna watershed.

History of Mining and
of AMD Discharge
The Lancashire 15
mine-pool complex is
composed of 15 major
underground mines
and several smaller
ones covering a total
of about 12,000 acres.
Mining began about
1888 and continued
until the mid 1980s
when the last major
underground mines
closed. Early mining
within the study area
was conventional
room-and-pillar with
extensive retreat
mining; the more
recent mining has
been a combination
of room-and-pillar
and longwall mining.
Many of the mines
in the Lancashire 15
mine-pool complex are
interconnected or have
relatively thin barrier
pillars.
The main mine
of interest in the
complex is the Barnes
& Tucker Lancashire
15. When this mine
closed, dewatering
pumps were shut
off in 1969 and the
mineworks were
allowed to fl ood. By
1970, the mine began
to discharge AMD
impacted water along
its northern margin
into the West Branch
of the Susquehanna.
A decline in water
quality was observed
for many miles
downstream from
the mine, prompting

Recent research has documented
that many chemical constituents
that were not historically considered
contaminants are present in the
environment. These “emerging
contaminates” include compounds
such as pharmaceuticals, antibiotics,
hormones, detergent metabolites,
fl ame retardants, and personal care
products. These compounds enter the
environment through various pathways
including municipal, agricultural, and
industrial wastewater sources. Limited
information is known regarding the
occurrence, transport, and fate of

Emerging Contaminate Compounds in Aquatic
Ecosystems
many of the organic chemicals after
their intended use. Many of these
compounds are not currently regulated
by drinking-water standards or human
or aquatic-life health criteria. Potential
concerns from the environmental
presence of these compounds include
physiological and reproductive
impairment, increased cancer rates,
and the development of antibioticresistant
bacteria. The potential eff ects
on human and aquatic ecosystems are
not clearly understood.
Little data exist on the occurrence
of these compounds in aquatic
ecosystems because they are usually
found at concentrations below
the detection limits of established
analytical methods. New analytical
methods have recently been developed
that can detect these synthetic organic
compounds at the low concentrations
which they might be expected in the
environment.
The United States Geological Survey
(USGS) has begun research on
analytical methods and reconnaissance
data collection to help determine the
distribution and concentration of these
Contaminants continued on page 9

“emerging contaminate” compounds
in various aquatic ecosystems. A
national reconnaissance in 1999-
2000 found that 82 of the 95 organic
wastewater compounds (OWCs)
analyzed were detected in 80% of
the 139 streams sampled. In the 139
samples the median number of OWCs
detected was 7 with a maximum of
38. The most commonly detected
compounds were steroids, antibiotics,
non-prescription drugs, caff eine, and
insect repellents. Although these
sites were selected because they
were close to wastewater discharges
or large livestock operations the
study demonstrates the presence
of these compounds at detectable
concentrations throughout the United
States

the Commonwealth to conduct
emergency water treatment at the
site.
In 1973 the Barnes and Tucker
Company began pumping and
treating mine water at the Duman
site, in the southern end of the
mine-pool, water levels were lowered
below discharge elevation, and
AMD ceased. The pump-and-treat
operation established suffi cient
by chemical contaminants, resulting
in development and reproductive
problems. For example, feminization
of fi sh and intersex fi sh are common
in the Potomac River Basin and
elsewhere. High levels of vitellogenin
(an egg protein normally found in
females) have been detected in male
fi sh exposed to wastewater effl uent.
Few data exist from Pennsylvania
waters to document the occurrence and
distribution of OWCs and the presence
of intersex fi sh. Studies are needed to
determine whether these compounds
are present and, if so, which
compounds, at what concentrations,
and what are the environmental and
health implications.
The USGS and the Pennsylvania
Department of Environmental
Protection have begun a
reconnaissance data collection
program to document the occurrence
and concentration of OWCs in surface
drawdown that diverts the impaired
water from the Susquehanna basin to
the Duman facility in the Ohio basin
(about 6,500 gallons per minute are
treated at Duman and released into
the Blacklick Creek in the Ohio basin).
The Barnes and Tucker treatment
fund was exhausted in 2001 and
the company declared bankruptcy.
The Commonwealth assumed the
responsibility for the treatment in
2001 and has continued to maintain
the system since.

of wastewater facilities and near
drinking water intakes. Groundwater
samples are also being collected in
agricultural areas and near septic
fi elds. The sampling program also
includes evaluation of fi sh health
related to reproductive problems such
as intersex fi sh (Figure 1). Plasma is
obtained from each fi sh and analyzed
for reproductive hormones, thyroid
hormone, cortisol, and vitellogenin.
The fi sh are dissected and pieces of
liver, spleen, kidney, gill, and gonad
are observed for abnormalities and
retained for histological analyses.
Surface water sampling and fi sh
health evaluation began in 2007 and
is scheduled to continue until 2009.
Sampling locations in the Delaware
River Basin include the Delaware
River at Trenton, Schuylkill River at
Philadelphia, Broadhead Creek near
Stroudsburg, and Jordan Creek at
Allentown.
Remediation Project and Benefi ts
In the Susquehanna basin, AMD
is among the leading sources of
pollution, and nowhere is that
problem more prevalent than in the
West Branch. The Commonwealth
identifi ed the West Branch as a
priority waterway and has devoted
signifi cant fi nances and technical
support toward its remediation
This new Barnes and Tucker facility
would:
• Restore the natural fl ow of
the discharge back into the
Susquehanna watershed.
• Treat and release 10 million gallons
of water per day in the West Branch,
resulting in the restoration of 25
miles of the AMD-impaired river.
• Allow SRBC to secure 10 of the 15.7
million gallons of water per day
needed to mitigate the impact
of the consumptive water use
by agricultural operations in the
Pennsylvania portion of the basin.
